Description and Introduction

4-Bit Synchronous Up/Down Binary Counters The SN74ALS169BNSR is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Up/Down Binary Counter  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** 16-SOIC (150 mil)  
- **Mounting Type:** Surface Mount  
- **Number of Bits:** 4  
- **Trigger Type:** Positive Edge  
- **Count Rate:** 35 MHz  
- **Output Type:** Standard  
- **Propagation Delay Time:** 15 ns (typical)  
- **Current - Output High, Low:** 2.6mA, 24mA  
- **Features:** Synchronous counting, parallel load capability, carry lookahead for cascading  

### **Descriptions:**  
The SN74ALS169BNSR is a synchronous 4-bit up/down counter with a parallel load feature, allowing for preset inputs. It operates synchronously with the clock and can count up or down based on control inputs.  

### **Features:**  
- Synchronous counting operation  
- Parallel load capability  
- Carry output for cascading  
- Fully programmable (count, load, or hold modes)  
- Low power consumption (ALS technology)  
- High-speed operation (35 MHz typical)  

This information is based on TI's official datasheet for the SN74ALS169BNSR.
